使用ng-option——

以及select中加入自定义指令  convert-to-number

.directive('convertToNumber', function () {    return {        require: 'ngModel',        link: function link(scope, element, attrs, ngModel) {            ngModel.$parsers.push(function (val) {                return parseInt(val, 10);            });            ngModel.$formatters.push(function (val) {                return '' + val;            });        }    };});
